I recently tried to discover what was the original Rpm limit of a 3.6 M5, cause i had a impression that mine was a bit higher... well, yesterday i saw it in detail! it does 8000 RPM!!! then cuts off...
I have the car for 2 months now... i thought it was 100% stock... well, it doesnt seme so...
Is it a simple agressive chip?
Help please...
